OH YES, FINALLY! That is why!!!

Ok sorry but finally woot! Sorry, I'm new to C. And I feel stupid now

Hmm.. ok lol, new problem now.

It's a little different than before. The difference here is that the compiler is giving me errors when I try to include my global.h file which conains all of my global variables.

Whenver I include:
"global.h"

in the "intro.cpp" file,
it says its already been defined from cosmosII_client.cpp
error:

Code:

1>intro.obj : error LNK2005: "int arenaGen" (?arenaGen@@3HA) already defined in cosmosII_client.obj
1>intro.obj : error LNK2005: "int arenaTimeNum" (?arenaTimeNum@@3HA) already defined in cosmosII_client.obj
1>C:\Documents and Settings\Keenan\My Documents\Visual Studio 2005\Projects\CosmosII\Debug\CosmosII.exe : fatal error LNK1169: one or more multiply defined symbols found

ect...

But if I take out global.h in the "intro.cpp" file it cant find the variables at all and will say this:

Code:

1>.\intro.cpp(109) : error C2065: 'part' : undeclared identifier
1>.\intro.cpp(123) : error C2065: 'diag_1' : undeclared identifier
1>.\intro.cpp(134) : error C2070: ''unknown-type'': illegal sizeof operand

ect... (it doesnt see the variables in global.h!

WHAT THE FILES LOOK LIKE:

Code:

intro.cpp:

// intro.cpp

#include <windows.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <time.h>
#include <string.h>
#include <wincon.h>
#include <conio.h>
#include <iostream>
#include <iomanip>

#include "global.h"
#include "color.h"
#include "intro.h"

// prototypes
void main_menu(void); void user_name(void); void difficulty_select(void); void intro(void);
void game_logo(void); void intro_ask(void); void intro_part2(void); void logo(void);

// STARTUP FUNCTIONS:

void logo()
{
	dark_logo();system("cls");

	for(int intro_loop=0;intro_loop<26;intro_loop++)
	{
		Sleep(1);
		printf("\n\n");
	}
} //ect...

Code:

intro.h:

// intro.h

void intro(void);
void game_logo(void); 
void intro_ask(void); 
void intro_part2(void); 
void logo(void);

global.h:

Code:

// global.h

// _________________
// GLOBAL VARIABLES:

	extern char diag_1[]="In a galactic system far, far away...";
	extern int part=0;
   
   extern char difficultyString[7]="NONE";char typeString[11]="NONE";
   extern int difficulty=0,type=0; 
//ect...

cosmosII_client.cpp:

Code:

// COSMOS II - CLIENT (Build 0.00)

/* Coded by X
   Begun: April 6, 2006 | End: TBA */

#define _WIN32_WINNT WINVER

// include files

#include <windows.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <time.h>
#include <string.h>
#include <wincon.h>
#include <conio.h>
#include <iostream>
#include <iomanip>

#include "global.h"
#include "color.h"
#include "intro.h"


#ifdef WIN32
#endif

//ect...

in global.h, like this:

Code:

extern int arenaMaxTemp,arenaTemperature,timeGen,arenaWindVariance,arenaLowWind,
		arenaMaxWind,arenaWind,arenaTempVariance,arenaLowTemp,arenaFans,arenaForcastNum,
		arenaForcastRnd,arenaMaxRange,arenaNum,arenaGen,arenaTimeNum;

i actually have a lot more...

EDIT: ignorre spaces i didnt do that

hey, hey ,hey that works!
